I like 'em, I had a few 500's and 350's when I was a kid, I even had a 350 powered Go-Kart! It'd do 105 Mph in a straight line, trouble was, it was that heavy in back that it wouldn'y go around corners! I bought it off the owner/builder who sailed over a farm fence into a boggy paddock when it failed to go around a bend at maximum warp, and he was happy to take the 30 bucks I paid him for it!
The Brits had them made in India to save money on labour, and they have only just got back the right to use the "Royal" part of their name. The old factory kept pumping these bikes out for mainly local and "Other third world country" sales, and things like "Total Quality Control" were never practised, so the product suffered much like the English bikes of the 1970's, and that's where most of the bad feedback comes from.
They're still an "Aquired taste", but a true motorcycle lover will still enjoy one now, probably for the same reason we like our 30+ year old bikes, these things have survived from their original manufacture in the 1940's to now, with only minor concessions to modern expectations, like fancy "electric starters" and "electronic ignition" etc. Personally, I'd rather a 750 Interceptor, they were very fast, and easy to push when they inevitably broke down!
